Question 20

A number is greater than thrice its reciprocal by 26/3. What is the number?

Solution

Let the number be $$x$$

According to ques, => $$x - \frac{3}{x} = \frac{26}{3}$$

=> $$\frac{x^2 - 3}{x} = \frac{26}{3}$$

=> $$3x^2 - 9 = 26x$$

=> $$3x^2 - 26x - 9 = 0$$

=> $$3x^2 + 1x - 27x - 9 = 0$$

=> $$x(3x + 1) - 9(3x + 1) = 0$$

=> $$(3x + 1)(x - 9) = 0$$

=> $$x = 9 , \frac{-1}{3}$$

=> Ans - (C)
